How far can you reposition your hotspot on the map without causing any issues?

My house is near the boundary of 3 separate hexes which each have 3 devices. If my first device does well, I was thinking I could get two more and reposition them on the map so I add one to each hex, if that wouldn't cause any issues for myself or the network. The closest boundary for one hex is 950 feet and the other is 540 feet. One answer I saw said the limit is about 300m which is 984ish feet so... should be safe? Also would there be any negative impact on the network? Not trying to cheat but also trying to maximize any profit.
